【摘要】 利用180具小儿尸(男103,女77),分六个年龄组,观测其咽的形状、位置及有关结构.咽的位置(下界)随年龄(身长)的增长而下降,咽的长度以Ⅰ～Ⅲ组小儿增长较快,咽穹不明显,咽鼓管咽口的形态Ⅰ～Ⅲ组多为裂隙形,Ⅳ～Ⅵ组多为卵圆形,腭扁桃体呈规律性增长,咽扁桃体以Ⅲ组增长最快.更多还原

【Abstract】 180 pediatric cadavers (103 male, 77 females) divided into 6 groups were observed and measured in order to study the positions, shapes and relevant structurs of the pharynx.The position (lower limit) of the pharynx move down with the age increase. The lengths of pharynx inⅠ-Ⅲ　groups increase quickly comparatively. The fornix of pharynx are not obvious. The shapes of the pharyngeal opening of the auditory tubes are cleft-shaped in Ⅰ-Ⅲ groups and are oval in Ⅳ-Ⅵgroups. Palatine tonsils enlarge regularly. The enlargement of pharyngeal tonsils inⅠ-Ⅲ groups are the most rapid.更多还原
